Hail — Martin, Texas

2019-05-20 · near Stanton, Martin, Texas

Wider weather episode

An upper level trough was over the Great Basin during the morning hours and moved over the Rocky Mountains during the day. Upper level disturbances moved over West Texas along the edge of this upper trough. A surface trough was over far West Texas and resulted in an abundance of moisture across the area. The atmosphere quickly became unstable as temperatures warmed up at the surface. A dryline was backed up to the higher terrain of West Texas and southeast New Mexico with very good wind shear and atmospheric rotation in place. During the late evening hours, upper lift increased with the approaching upper trough and the area was in a favorable position for lift with the upper jet stream. A low-level jet stream also moved across the area providing more lift. A Pacific front associated with the upper trough moved east and interacted with the dryline to create additional lift. These conditions resulted in thunderstorms rapidly developing and becoming severe with large hail, strong and damaging winds, tornadoes, and flash flooding across West Texas.
